[PATCH 0/6] XFS update for 3.1-stable

This is a series of XFS fixes from current mainline which is important for
3.1-stable. Note that it is the same patch set that Christoph submitted for
3.0-stable, minus the first three patches which are already included in 3.1.
My QA came out ok with these six patches atop 3.1.y. Apologies to those who
got this mail twice.
Thanks,
Ben
